The first was that Bieber wore a custom-made Cavs jersey with his name and No. 6 on the back. Good move to win over the Cleveland crowd, right? But it seems that Bieber is now aboard the team train to go all the way. Fans may have mixed feelings about that, but the more fans the better, right?

In another shocker, Johnny Manziel, the extremely bad boy recently cut by the Cleveland Browns, made a guest appearance. It happened on the same day he was formally indicted by a Texas grand jury for alleged assault against his ex-girlfriend. Obviously, Manziel isn't worried about the case and would rather spend time with friends at the Biebs concert. Incidentally, one of those friends was Browns cornerback Joe Haden.
